Ajax，异步JavaScript与XML，是使用客户端脚本与Web服务器交换数据的Web应用开发方法。这样，Web页面不用打断交互流程进行重新加裁，就可以动态地更新。使用Ajax，你可以创建接近本地桌面应用的，直接的、高可用的、更丰富的、更动态的Web用户接口界面。
Ajax处理过程
一个Ajax交互从一个称为XMLHttpRequest的JavaScript ......
log into file
//
ob_start();
echo "<pre>";
print_r($data);
echo "</pre>";
$a=ob_get_contents();
//DAL::remove("insert into mytest(vvv) values('$a')");
$filename = "file.txt";
$file = fopen($filename, "w") ......
